Sheep or lonely

Hello Susan, Glad you enjoyed your break. It`s the "herding instinct" I`m afraid!

As a family we once sat on an empty beach and another family appeared and sat beside us! So yes, would agree with the herding instinct or maybe safety in numbers!

Its because they obviously knew that you had selected the best pitch on the site and wanted to be as close as possible to it. 

I know what you mean. We were on a very quiet site in France. We pitched under some trees and were the only people in that area, It was lovely and peaceful. Imagine the surprise when we woke up in the morning to the chatter of foreign voices and clanking of dishes. I peeped out of the window and there was a circle of 8 caravans parked next to us all with Dutch number plates having a communal breakfast. The rest of the site was almost deserted. We assume they must have felt safe next to an English contingency !!
